Description

Chilling roller oil scraping knife with adjustable contact pressure

Technical Field

The utility model relates to a chill roll oil scraping knife particularly, relates to a chill roll oil scraping knife with adjustable contact pressure.

Background

The lithium ion battery diaphragm is mainly prepared by a wet method, which is also called a thermal phase separation method, at present, liquid hydrocarbon or micromolecule substances are mixed with polyolefin resin, a uniform mixture is formed after heating and melting, then the temperature is reduced for phase separation, a diaphragm is obtained by pressing, the diaphragm is heated to the temperature close to the melting point, bidirectional stretching is carried out for molecular chain orientation, finally, the temperature is kept for a certain time, and the residual solvent is eluted by volatile substances, so that the microporous membrane which is communicated with each other is prepared.

In the production of current wet process lithium cell diaphragm, the fuse-element is from die head curtain coating to chill roll on, the chill roll can remain a large amount of white oil when cooling the diaphragm, need use elastic frizing sword to strike off the roll surface white oil totally, because machining precision or other reasons, the frizing sword often can't laminate with the chill roll completely in the production process, leads to the roll surface to have the white oil to remain, influences product appearance performance. The reason for this is that the scraper is elastic and deformable, and the contact pressure between the scraper and the chill roll is not sufficient, so that the scraper cannot be 100% adhered to the roll surface.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a chill roll frizing with adjustable contact pressure can adjust the contact pressure of each position and chill roll on the blade alone, makes the surface of frizing and chill roll fully laminate, eliminates the white oil residue on chill roll surface.

Therefore, the utility model provides a chill roll frizing sword with adjustable contact pressure, include: the bottom of the tool holder is provided with a clamping groove, the blade is fixedly installed below the tool holder, the blade comprises a tool back and a cutting edge, the tool back is clamped in the clamping groove, the cutting edge abuts against the surface of the chilling roller, a plurality of adjusting bolts are arranged above the tool holder along the length direction, the adjusting bolts penetrate through an upper frame of the tool holder, and the end portions of the adjusting bolts abut against the tool back.

Further, the blade is a soft rubber and plastic knife.

Further, the length of the blade is greater than the length of the chill roller.

Further, the two ends of the blade in the length direction are fixedly installed in the clamping grooves through bolts.

Further, the width of the clamping groove is equal to that of the knife back.

Further, a plurality of adjusting bolts are arranged in parallel and equidistantly on the tool holder.

The utility model provides a chill roll frizing sword with adjustable contact pressure, include: the bottom of the tool holder is provided with a clamping groove, the blade is fixedly installed below the tool holder, the blade comprises a tool back and a cutting edge, the tool back is clamped in the clamping groove, the cutting edge abuts against the surface of the chilling roller, a plurality of adjusting bolts are arranged above the tool holder along the length direction, the adjusting bolts penetrate through an upper frame of the tool holder, and the end portions of the adjusting bolts abut against the tool back. The soft rubber plastic knife is used as the blade of the oil scraping knife, and when the cutting edge of the blade cannot be attached to the surface of the chill roll in percentage, the blade can be adjusted through an adjusting bolt arranged on the knife holder. When the contact pressure between a certain point on the blade and the surface of the chill roll is insufficient, the adjusting bolt positioned right above the blade can be adjusted, and the adjusting bolt applies pressure to the blade back of the blade, so that the contact pressure between the point and the surface of the chill roll is increased, and the point is fully attached to the surface of the chill roll.

The utility model provides a pair of chill roll frizing sword with adjustable contact pressure can be adjusted the contact pressure of each position and chill roll on the blade alone, makes the surface of frizing sword and chill roll fully laminate, and the white oil on elimination chill roll surface remains.
